摘要
研究了用聚苯乙烯废料为原料，经过硝化氧化制造具有高附加值的精细化工产品——对硝基苯甲酸。探讨了影响对硝基苯甲酸产率的因素，如硝酸的浓度和用量、压力、反应时间及催化剂用量等。结果表明，在优化条件下对硝基苯甲酸产率达５２％，产品纯度为９９％
The preparation of p nitrobenzoic acid, a fine chemical product with a high added va lue , from waste polystyrene by nitration oxidation was studied. The affecting factors such as concentration and dosage of nitric acid, reaction pressure, reaction time and catalyst dose were investigated. The yield and the purity of p nitrobenzoic acid were 52% and 99% respectively under the optimum conditions.
